I just purchased an HP 23" LED IPS monitor for $199, and they even gave me a $15 credit since I called and asked "any specials?". Both those monitors are nice but an IPS monitor will blow either one of those away.
I have the vs248 and it is not ips quality. But it is really good for a tn. You must not have used a good ips monitor. I can't find a proper review of the samsung so I can't really say for sure. But I don't think you can go wrong with either looking as similar samsung model reviews.
Huge +1 here for buying an IPS panel monitor. I actually stuck with a big old CRT until I got IPS. I purchased several TN panels before my IPS but returned them all because I couldn't accept the loss of colour quality/accuracy compared to my CRT (it was a nice CRT though!).
